Cardioprotective effect of spirulina on cafeteria diet-induced cardiac injury in silico and in vivo study.
Article in Journal of the science of food and agriculture, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundObesity is a major risk factor for cardiovascular disease, primarily due to its effects on lipid metabolism, oxidative stress, and inflammation. The aim of this study was to evaluate the effects of spirulina (SP) on cafeteria diet (CD)-induced myocardial oxidative stress and inflammation using biochemical, histological, and in silico molecular docking approaches. This study integrates in vivo biochemical and histological analyses with in silico absorption, distribution, metabolism, excretion, and toxicity (ADMET) profiling of spirulina (SP)-derived phenolic compounds (resorcinol, chlorogenic acid, catechin, syringic acid, sinapic acid, and quercetin) to evaluate the cardioprotective effects of SP. Wistar rats were divided into four groups (n = 8 per group), and treatments were administered orally once daily for 8 weeks as follows: standard diet (SD) (360 g day⁻¹), CD (360 g day⁻¹), CD + SP (500 mg kg
resultsRats fed with CD exhibited significant weight gain (21.38%), dyslipidemia, increased myocardial oxidative stress, elevated gamma-glutamyl transferase (γ-GT) (1.57 U L), and reduced antioxidant defenses. Inflammatory cytokines were markedly upregulated, and histological analysis revealed cardiomyocyte hypertrophy and inflammatory cell infiltration. Spirulina supplementation effectively ameliorated these alterations by improving weight gain (9.85%), lipid profiles, attenuating oxidative stress, reducing γ-GT (0.83 U L), and downregulating inflammatory responses (P < 0.05). Histological observations confirmed the preservation of myocardial architecture. In silico analysis further demonstrated strong binding affinities between SP phenolic compounds and SOD, and ADMET profiling highlighted their potential - particularly in the cases of catechin, chlorogenic acid, and syringic acid - as safe and effective modulators.
conclusionSpirulina exerts significant cardioprotective effects against CD-induced myocardial injury by modulating oxidative stress and inflammation, indicating its potential as a natural therapeutic agent for obesity-related cardiovascular disorders. © 2026 The Author(s).
